Grammar in use-虚拟语气

Grammar in use-虚拟语气

语气是表示说话者对动词所表示的动作或状态的态度的一种动词形式。

英语中有三种语气：直陈语气、祈使语气和虚拟语气。

虚拟语气是表示说话人一种主观愿望、假想或建议。

一、真实条件和非真实条件英语中的条件句分为真实条件和非真实条件。

真实条件表示现实情况中可能实现的情况，而非真实条件表示与现实情况相反的假想情况。

（真实条件）如果工作条件不太差，我会接受这项工作。

If the working conditions are not too bad, I will accept the job.（非真实条件）如果工作条件不太差，我就接受这项工作了。

If the working conditions were not too bad, I would accept the job.（事实是The working conditions are too bad, so I won't accept the job.）（真实条件）他说他如果失败，他还会再试一次。

He said if he failed, he would have another try.（非真实条件）如果他失败的话，他会再试一次的。

If he had failed, he would have had another try.（事实是He didn't fail and he didn't have another try.）二、非真实条件句1.与现在事实相反If从句：动词过去时（be动词用were，但在口语中，在单数第一、三人称后也有用was。

）主句：would/should/could/might + 原形动词如果房间大一点的话，我们就在那儿举行聚会了。

If the room were larger, we would hold the party there.假如我身边有钱，我就借点给你。

If I had money on me, I would lend you some.2.与过去事实相反If从句：had + 过去分词主句：would/should/could/might have + 过去分词如果那个地方不远的话，我们就步行去那儿了。

而且，我们在日常对话中也会经常用到虚拟语气。

四、知能提升〔一〕知识讲解【认知讲解】教材原句呈现①If you were an artist, what kind of pictures would you paint?②If the rules of perspective had not been discovered, no one would have been able to paint such realistic pictures.③Have you ever wished you could paint as well as a professional artist?比照分析第一个句子中的从句显然是做了一个不可能成立的假设，这是一个与现在事实相反的虚拟语气的句子。

第二个句子中如此是与过去事实相反，是表示如果透视法没有被发现，就没有人能够画出这样具有现实主义的画来。

第三个句子中wish后面的虚拟语气，表示与将来事实相反。

【重、难点】1〕虚拟语气可以用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。

虚拟语气在条件句中应用得比拟多。

2〕条件句可分为两类，一类为真实条件句，一类为非真实条件句。

非真实条件句表示的是假设的或实际发生的可能性不大的情况，故采用虚拟语气。

I.真实条件句用于陈述语气，所假设的情况有可能发生。

结构如下所示：从句往往用一般现在时，而主句如此由“shall/will + 动词原形〞构成。

虚拟语气在非真实条件句中的应用
Ⅰ if条件句的虚拟语气
if的非真实条件从句对现在,过去,将来的事实进行虚拟时,主句和if从 句的谓语动词形式如下: 1.与现在事实相反时,其表现形式为:
The subjunctive form
The what?
The subjunctive form sounds scarier than it actually is. The subjunctive form is mostly used in formal language (if you were the queen for example). It can be used to give advice of talk about unreal situations.
ahead of time. (3)含有助动词should的虚拟条件句，也可用在主句是陈述语气或祈使 语气的句子中. Eg :If there should be another flood, what should we do?
Ask her to leave a message if she should come. (4)supposing, suppose, even if也可引导虚拟条件句。 Eg :Supposing it were fine tomorrow, would you go swimming with us? (5)有时suppose或supposing单独引起一个句子，用于提出建议或假设。 Eg :Suppose we started tomorrow.
The detective insisted that he should have a look.
. (3)表语从句或同位语从句 在advice, command, demand, desire, idea, motion, order, plan等名词作主语的表语 从句或同位语从句中，谓语动词用should be型或be型虚拟式。 Eg :The doctor’s advice is that the patient should be kept quiet. He rejected my advice that he should meet my son. 在as if 引导的表示虚拟的表语从句中，谓语动词用were型虚拟式表示对现在情况的 假设，用 had been型虚拟式表示对过去情况的假设。 Eg :You look as if you had a toothache. 如果说话人所表示的不是假设的情况，而是一种可能的事实，as if引导的表语从句 中的谓语动词使用陈述语气。 Eg :It looks as if it is going to rain. 在主句的谓语动词为过去时的情况下，往往无法从语法形式上辨别表语从句的谓语 动词是虚拟还是陈述语气，因为此时两者的形式是相同的。 Eg: She looked as if she had had some bad news.
Or
• We have asked for the match to be postponed due to the rain.
Which is written in the subjunctive?
• Honesty is part of our school rules. Or
• Our school rules require that all children be honest.
I wouldn’t have known what these were for if I hadn’t been told.
Ⅱ 错综时间句的虚拟语气
当条件从句与结果主句所表的时间不一致时,虚拟语气的形 式应当做相应的调整.如: (1) If I had spoken to him yesterday, I should know what to do now. (2) You would be much better now if you had taken my advice. (3) If father hadn’t sent me, I shouldn’t be here. (4) If he knew this, it would have had to be by accident. 如条件从句用if I were…,结果主句则可用表任何时间的虚拟 形式.如: (5)If I were not easy, I would have come. (6)If I were you, I would go. 根据句意的需要,有的句子的主句为陈述语气,而从句为虚拟 语气.如: If this machine should fail to give satisfaction, we guarantee to refund the
